[英]PDFKit not generating correct PDF
I installed PDFKit and wkhtmltopdf. 我安装了PDFKit和wkhtmltopdf。
In one action I render a simple html like: 在一个动作中,我呈现了一个简单的html,例如:
<html><body><h1>Hello Internet!</h1></body></html>
When I run my action with .pdf extension it generates a wrong pdf file. 当我使用.pdf扩展名运行我的操作时,它将生成错误的pdf文件。 Debugging PDFKit I got to these lines:
调试PDFKit我有以下几行:
result = IO.popen(invoke, "w+") do |pdf|
pdf.puts(@source.to_s) if @source.html?
pdf.close_write
pdf.gets(nil)
end
Well, this is where my PDF is generated, it uses a command line no wkhtmltopdf and my html as input. 好的,这就是生成我的PDF的地方,它使用的命令行没有wkhtmltopdf,而我的html作为输入。
Using rdebug I found that the value for invoke is: 使用rdebug,我发现invoke的值是:
"c:\Program Files\wkhtmltopdf\wkhtmltopdf.exe" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-" "-"
And @source.to_s is @ source.to_s是
<html><body><h1>Hello Internet!</h1></body></html>
Ok, so I tried to run the command by hand like this: 好的,所以我尝试像这样手动运行命令:
"c:\Program Files\wkhtmltopdf\wkhtmltopdf.exe" "--margin-right" "0.75in" "--page-size" "Letter" "--margin-top" "0.75in" "--margin-bottom" "0.75in" "--encoding" "UTF-8" "--margin-left" "0.75in" "--quiet" "-" "-" < c:\hello_internet.html > correct.pdf
Obviously in hello_internet there is the content of @source.to_s 显然在hello_internet中有@ source.to_s的内容
Running it results in the correct pdf being generated. 运行它会生成正确的pdf。
The correct pdf generated is here and the wrong is here . 正确的pdf 在这里 ,错误的在这里 。
I have no idea what can be wrong here. 我不知道这里有什么问题。
Thanks. 谢谢。
该解决方案非常简单,是PDFKits Github上bxu689 提出拉取请求的对象。
